LOCK FOR CONTROLLING LEVER S.-

Application filed March 6, 1917. Serial no. 152,927.

To all whom it may concern:

Be it known that we, Hnnny J. MENARD and AUGUSTUS C. SAx'roN, citizensof the United States, and residing at Chicago, Illinois, have inventedcertain new and useful Improvements in Looks for Controlling Levers, ofwhich the following is a specification.

This invention relates to looks for controlling levers, and is animprovement upon the invention described in our copending applications.

It is'one object of the invention to so modify and rearrange the partsof our prior ples of operation to. a lever which must be supported orheld up,

In the drawings v Fig. l is a sectional-elevation of a lock constructedaccording to our invention.

Fig. 2 is a sectional elevationof the same lock upon a plane at rightangles to that of Fig; 1. Q i

Fig. 3v is a detail sectional elevationof the lock.

Fig. 4 is a cross of. Fig. 2.

Fi 5 is a cross sectional elevation upon the line 5-5 of Fig.2.

1 represents in general the transmission sectionupon the line casing.(of the Buick type, for instance,) inwhich is provided an mterruptedspherical shaped casing, in whichis mounted the ball -2 of thecontrollin lever 3, the lever being passed upwardly t rough thetransmission casing, and supported upon the casing.

We provide a conical, preferably, shaped recess 4 in the transmissioncasing for the passage of the lever, and upon the controlling leverimmediately above the ball 2 thereof, we have mounted a slidable sleeve5,

having at'its lower end an integrally formed disc 6, which has a taperto correspond with the taper of the conical shaped recess 4. Mounted onthe substantially spherical outer surface 7 of the transmission casingis a correspondingly shaped cap member 8, having the spherical flange 9.The member 8 performs the function of supporting the lever and simplymoves overthe top of the spherical casing'as the lever-ismoved inoperation in the fashion indicated in Figure 3.

Slidably mounted upon the upwardly extending sleeve 8' of thecap member8,

which is rigidly mounted upon the lever 3,

is the lock casing 10,'containing a spring pressed plunger 11, operatedby means of a cam 12, controlled by the tumbler lock 13,

in a m anner sufliciently *obvious from the drawings. The sleeve 8 hasnear its upper end an annular notch 15, and'nea'r its lower end at leastone aperture 16 of the size to reeeive'the bolt 11. The slidable casing10 is mounted upon the sleeve 8', so that it may :move "freely up anddown thereon, the construction being such that-when the bolt 11 isretracted by means of the key operated cam 12, the casing 10 is free tomove up.

and down upon thesleeve 8'," but when the casing. 10 is moved downwardly(without turning the key) the bo lt will spring into the aperture16,-lockin the casing 10 in its downward. position; t will be noted thatcap member 8 is under cut as indicated at '17, for the reception of theslidable lever looking. member 5-6. -Mounted upon the disc 6 of thismember are a pair of vertically extending bolts. 20 which pass throughholes drilled in the cap member 8,and into larger.

holes drilled in the slidable member 10, and

are surrounded by the compression springs.

21, bearing at one end against the bee 220i the bolts, and at the otherend against the top cap member 8. It will be noted that direct downwardpressure can thus be communicated to the sleeve 5 of the disc shapedmember 6 by pushing downwardly upon the slidable casing'lO, which isdrilled out to accommodate the bolts 20 "and surrounding springs. Theswivel ends 23 of the drill holes in' the casing 10 impinge directlyupon the heads of the bolts and may thus positively push down the leverlocking member 5-6. This locks the controlling lever by the engagementby plugging the conical recess 4 with the disc member '6, preventing themovement of the lever.

When the lock casing 10 has been pushed downwardly (thekey', of course,being removed,) the bolt 11 automatically snaps into the recess 16 inthe sleeve 8', absolutely locking the lever. When the key is insertedand momentarily turned, the bolt 11 is retracted. The springs 21 thencome into operation to automatically raise the locking case 10, in whichevent the bolt 11 rides upwardly and catches in the notch 15, preventingthe lock casing from being pulled up on the handle of the controllinglever, unless it is desired to do so, in which event the pressure uponthe key is maintained,

the bolt 11 being kept freely retracted. so

that the lock casing may be raised as far as desired upon thecontrolling, lever. In

normal operation, however, the lock casing 10 will be caught b springs22 automaticall this position.

It is to be particularly noted that the disc member 6 when the key ismomentarily turned iscarried up by the same springs 21 which act uponbolts 22 andpasses into a -liormed seat in the bottom of the member thenotch 15, the pushing it up into 8, as shown in Figure 3, in which eventit is well above thetop of the spherical transmission casing 7 andcannot interfere with the operation of the machine1- It is, of course,obvious that it is'not necessary to the realization of. the majorfeatures of this invention,- for the disc shaped.

member to be provided with a conical face; a cylindrical member engagingin a cylindrical recess in the transmission. casing would also serve, orthe lower face 6' of the disc shaped member 6 could be made to directlyabut the shoulder 2' of the lever and thus lock the same. 7

The construction just described affords a simple, compact, convenient,and extremely efiicient lock for levers of the kind herein described,

Having now described our invention 1 c ann:-
